# The verification mechanism is the critical enabler that distinguishes binding-in-practice from binding-in-text arms control — the BWC banned biological weapons without verification and is effectively voluntary while the CWC with OPCW inspections achieves compliance — establishing verification feasibility as the load-bearing condition for any future AI weapons governance regime

The Biological Weapons Convention (1975) and Chemical Weapons Convention (1997) provide a natural experiment for isolating the critical variable in arms control effectiveness. Both conventions:
- Apply to all signatories including military programs
- Contain no great-power carve-out in treaty text
- Ban production, stockpiling, and use of the weapons class
- Achieved near-universal ratification

The only meaningful structural difference: the CWC established the Organisation for the Prohibition of Chemical Weapons (OPCW) with binding inspection rights over declared national military facilities, while the BWC has no verification mechanism, no compliance assessment organization, and no inspection rights.

The outcome difference is stark: The CWC has documented compliance including US, Russia, China, UK, and France declaring and destroying chemical weapons stockpiles under OPCW oversight. Syrian non-compliance was investigated and documented (2018-2019 OPCW Fact-Finding Mission and Investigation and Identification Team reports), attribution reports issued, and sanctions applied. The BWC, despite being binding in text, is effectively voluntary in practice — the treaty banned the weapons while preserving state sovereignty over verification.

This comparison suggests verification feasibility is not just one of three equal enabling conditions for overcoming the legislative ceiling — it may be the most critical. Stigmatization and reduced strategic utility were already present for biological weapons: they're largely considered illegitimate (biological warfare has similar WWI-era horror associations as chemical weapons), and they have limited precision utility versus conventional weapons (biological agents are difficult to control and target). Yet the BWC still fails to achieve binding compliance due to the absence of verification.

For AI weapons governance, this establishes verification feasibility as the load-bearing condition. The implication: interpretability research that produces capability certificates legible to external inspectors is not just a technical AI safety priority — it's a prerequisite for any future governance regime that aims to be binding-in-practice rather than binding-in-text. Without a technical pathway to OPCW-equivalent verification for AI systems, any international AI weapons treaty will likely follow the BWC pattern (textual commitment without enforcement) rather than the CWC pattern (verified compliance).

The current state of AI interpretability research does not provide a clear pathway to this kind of external verification within policy-relevant timeframes. This is the technical bottleneck that makes the legislative ceiling practically insurmountable in the near-to-medium term, even if normative and strategic conditions were to shift favorably.

Physical compliance demonstrability for AI weapons varies by category. High-utility AI (targeting, ISR) has near-zero demonstrability (software-defined, classified infrastructure, no external assessment possible). Medium-utility AI (loitering munitions, autonomous naval mines) has MEDIUM demonstrability because they are discrete physical objects with manageable stockpile inventories — analogous to landmines under Ottawa Treaty. This creates substitutability: low strategic utility plus physical compliance demonstrability can enable binding instruments even without sophisticated verification technology. The Ottawa Treaty succeeded with stockpile destruction reporting, not OPCW-equivalent inspections.

Verification feasibility is a specific instance of Condition 4 (physical manifestation / infrastructure chokepoint). The BWC-CWC comparison shows that verification works when the regulated technology has physical manifestation: chemical weapons are physical stockpiles verifiable by inspection (OPCW), while biological weapons are dual-use laboratory capabilities that are much harder to verify. AI governance faces the same challenge as the BWC: AI capability is software, non-physical, replicable at zero cost, with no infrastructure chokepoint comparable to chemical stockpiles. This explains why verification mechanisms that worked for chemical weapons are unlikely to work for AI without fundamental changes to AI deployment architecture (e.g., mandatory cloud deployment with inspection access).
